Recently I've answered several peoples wants with zero response to my PMs - not bothered if its to say yes thanks, no thanks or kissmyarse - it's just polite to acknowledge receipt of the message.
Therefore I've now decided to respond to any want directly on the thread.
I'll list price, condition and bang up a scan if I can be bothered.
This way it opens the "want" up to other potential buyers, and the person posting the "want" might be less inclined to fanny around.
Breath in, breath out.
and relax.......
